Hello,

I got something really strange with my extension (which install a NPAPI plugin). I was used to update maxVersion property of the install.rdf every time a new major version of Firefox was released.

Today, I wanted to give a try of installing the extension with a too lower maxVersion value. I was extremely surprised to see that Firefox accepted it. I was able to drop the maxVersion value down to "4.*" (lesser it says that Firefox is not compatible).

I got it under Fedora and Windows.

Here is my install.rdf:
